Development of General-Purpose Software to Analyze the Static Thermal Characteristic of Nuclear Power Generation System

We have developed a general-purpose software by which static thermal characteristics of a power generation system can be analyzed easily. This software has following notable features. - It has new algorithm that can solve non-linear simultaneous equations used in analyzing static thermal characteristics of various power generation systems, namely the heat and mass balance and the efficiency. - It has flexibility over setting calculation conditions. - It can be executed on a personal computer easily and quickly. We have ensured that it can produce the heat and mass balance diagrams of a nuclear power plant’s main steam system and then it can calculate power output and efficiency of the system. Furthermore, we have evaluated various measures to recover heat from steam generator blowdown water and proved that this software is a useful operation aid for planning effective changes in support of power stretch.Copyright © 2008 by ASME
